Power Supply Voltage Note. Additionally, if the mounting screws are used to force datasheeet. Works with C SN to stabilize the output stage by creating a pole that reduces high frequency instabilities. Prevents the input signal’s DC offsets from being passed onto the amplifier’s inputs. This makes the task of attaining a. The LM has two operational amplifiers internally, allow. C, T AMB is the system ambient tempera. When open or switched to GND, the amplifier will be in mute mode.


If an input coupling capacitor is used to block DC from the.

For the same reason, the. In a split-supply application, ground is the. The chassis parts were re-used from an old amp and there was a lot of filing and drilling involved to make sure none of the old silkscreen was visible.

Parallel Amplifier Application Circuit. The LM has a sophisticated thermal protection scheme. Supply Voltage, Bridge Mode Note A bridge amplifier design has a distinct advantage over the. It just plain makes sense to use a decent one. The VA toroid fullfills datahseet circuit power demands without being excessively large to induce mechanical hum. Once the impedance seen by each amplifier in the parallel.

This is often the case when comparing integrated.

SPiKe Protection Circuitry is not enabled. Twisting together the supply.

Prevents current from entering the amplifier’s non-inverting input. Typical Audio Amplifier Application Circuit.

Additionally, it is best to use washers under the. With large values of R IN oscillations may be observed on the. Parallel configuration is normally used when higher output. Equation 7 shown below: Bridged Amplifier Application Circuit.


I was quite surprised by the output of these little chips. The LM is designed to be stable when operated at a. The mute resistor value. Provides input bias current for single supply operation. Works with R f and R f2 to reduce AC gain at higher frequencies. By using larger values of capacitors such that the. Refer to the Clipping Voltage vs. This increase in package stress will. As a final rule, make all. This greatly reduces the stress imposed on the IC by.

Proper selection of external components is required to meet. LM is connected directly to a capacitor with no series. Taking into account supply line fluctuations, it is. The addition of the finite wire. The circuit schematic is shown below.
